Possible GUI support ?

I am thinking of whether you could provide an GUI interface to us so that we can control the time when to start or end the code coverage analysis. For now, it starts code coverage analysis when application starts and end code coverage analysis when close the
application.

Is it possible to let us control when to start counting the code coverage? I imagine If has a GUI, then you might be able to add two buttons, like "Start" or "End" button. Then I think the tool would be more flexible to use because sometimes
I only want to get the code coverage report for certain actions in my application.

There is a plugin for Visual Studio. The plugin was not updated recently but improvements are in the
roadmap.
However there is no feature like start / stop. If you want to know to code executed when you click on a button, you can try to see if you can find code tracer (A tool that log all function call).
